The welding chip heats and melts the first welded part and the second welded part, and includes a projected part, a first extension part, and a second extension part. The projected part has a tubular shape with a bottom. One end of the tubular shape extending in a predetermined direction opens and the other end of the tubular shape is closed. The projected part is pushed into the first welded part and the second welded part in the predetermined direction from the opening one end of the tubular shape. The first extension part has a shape extending from a tube outer surface of the projected part and extending annularly around the predetermined direction. The second extension part has a shape extending from the first extension part to the opening one end of the projected part in the predetermined direction and extending annularly around the predetermined direction.

A laser welding method and system for joining portions of first and second workpieces of thermoplastic material that is partially permeable to a laser beam but absorbs radiation from the laser beam. The first and second workpieces, which are made of material that absorbs radiation from a laser beam, are clamped together. A mask is placed on a first surface of the first workpiece, the first surface being opposite the surface engaging the second workpiece. The mask is impermeable to a laser beam and forms a slot for passing a laser beam to the portion of the first surface of the upper workpiece exposed by the slot, so that heating and melting of the material of the workpieces is limited to the width of the slot. A laser beam is directed onto the slot and moved in a manner to illuminate the slot to melt and join the workpieces.

A method and a connecting element for joining two components, at least one of which is made of a fiber-reinforced composite, are proposed.

The present invention relates to a production machine for the production of collapsible pouches, which comprises an impulse sealing device with a first jaw and a second jaw for contacting bottom regions of walls of the pouches. Each jaw comprises a susceptor element comprising electrically conductive material, having a front surface that is at least shaped as an inverted T for sealing side edges and at least a portion of bottom edges of two adjacent interconnected pouches. Each jaw comprises an inductor which is electrically insulated from the respective susceptor element. The machine comprises a high frequency electric current source, which is connected to the inductors. At least one of the jaws comprises a cooling device for cooling down the respective inductor and susceptor element. The machine is configured so that, in an impulse sealing cycle for sealing the bottom regions of the pouch walls, the electric current source is operated to temporarily feed a high frequency electric current to the inductors, thereby generating a high frequency electromagnetic field with the inductors. The high frequency electromagnetic field induces eddy currents in the respective susceptor element generating an impulse of heat that is emitted by the susceptor element, which impulses of heat seal the bottom regions of the pouch walls to each other.

An electrode package includes an electrode pad to be attached to a subject, the electrode pad having a gel layer, a lead wire having one end electrically coupled to the gel layer, and a packaging cover having an opening portion, the opening portion being sealed such that the electrode pad and a part of the lead wire are housed inside the packaging cover. A sealing width in at least a part of a section where the packaging cover is sealed together with the lead wire is narrower than a sealing width in a section where only the packaging cover is sealed. A sealing apparatus is configured to seal the packaging cover.

A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.

A method includes compressing a non-dielectric, elastically-deformable component, a wire mesh component, and a dielectric, contoured object between first and second forming tools. Once the components are compressed, radio frequency energy is supplied to the first forming tool, thereby causing a radio frequency electromagnetic field to be generated between the first forming tool and the wire mesh component that results in a contoured weld of the contoured object. A tooling assembly is configured to carry out the method.

A welding apparatus for a fibre reinforced resin based material comprises an elongate flexible heat conductive strip and an elongate heat sink extending around at least a portion of the perimeter of the conductive strip. The elongate heat sink is divided into a plurality of segments wherein adjacent segments can move relative to one another.

An electrode package includes an electrode pad to be attached to a subject, the electrode pad having a gel layer, a lead wire having one end electrically coupled to the gel layer, and a packaging cover having an opening portion, the opening portion being sealed such that the electrode pad and a part of the lead wire are housed inside the packaging cover. A sealing width in at least a part of a section where the packaging cover is sealed together with the lead wire is narrower than a sealing width in a section where only the packaging cover is sealed. A sealing apparatus is configured to seal the packaging cover.

A method for producing a tube skirt for a flexible tube, said tube skirt being manufactured from a flat strip 1 comprising a decorative film 15 superimposed on a primary film 16, said primary film 16 comprising a sealable inner layer 14 at the lower surface 20 of the strip 1 as well as two stabilizing layers 11, 13, said decorative film 15 comprising a sealable outer layer 7 at the upper surface 19 of the strip 1, and a decorative layer 8, 9. This method comprises the following steps: winding the flat strip 1 into the form of a sleeve to shape the tube skirt; superimposing a first side border 2 of the strip 1 on a second side border 2 of the strip 1 to form an overlapping area 3, the sealable inner layer 14 of the primary film 16 of the first side border 2 overlapping the sealable outer layer 7 of the decorative film 15 of the second side border 2; applying a heating temperature T2 to the inside of the tube skirt at the inner face 22 of the overlapping area 3 to produce the side weld of the tube skirt; simultaneously with the application of the heating temperature T2, applying compression between the outer 21 and inner 22 faces of the overlapping area 3 so as to finalize the side weld of the tube skirt.
